PACKAGE-FILLING MACHINE.

Specification of Letters Patent.

Patented Mar. 16, 1915.

Application filed January 5, 1914. Serial No. 810,501.

To all whom it may concern.

Be it known that I, NATHAN MUsHER, a citizen of the United States, andresiding at Washington, in the District of Columbia, have inventedcertain new and useful Improvements in Package-Filling Machines, ofwhich the following is a specification.

This invention relates to package-filling machines, and moreparticularly to machines especially designed for filling cans with oilor other liquids.

The improvements are adapted for machines employing revoluble supportsfor the cans to be filled, and the main object of the invention is toprovide novel and effective means for elevating the cans to the fillingposition and automatically lowering them to permit of their readyremoval from the machine after filling.

The invention comprises a stationary cam shaped track-way in combinationwith a revoluble table, independent vertically-movable rods carryingwheels on rollers adapted to travel on said track-way, a valvecontrolling the flow of oil to the cans, and means for turning saidvalve by the revolution of the table.

The invention also includes novel means for holding the cans in positionabove the vertically-movable rods, said can holders being readilyremovable from the machine, and so constructed as to dispose of anyoverflow or drip from the can and thus prevent gumming or clogging ofthe holder.

The construction of the machine will be fully described hereinafter inconnection with the accompanying drawings which form a part of thisspecification, and its novel features will be set forth and defined inthe appended claims.

In the drawing: Figure 1 is a top plan view partly in horizontal sectionof a machine embodying the invention. Fig. 2 is a vertical sectionalview of the same. Fig. 3 is an elevation of the cam-faced track-wayemployed. Fig. a is a view in perspective of one of the improved canholders employed, and, Fig. 5 is a central vertical section of the same.

and incloses the gear wheel 3 and worm shaft 4, the shaft having anannular shoulder 7 resting upon the ball-bearings 8. A spider hub 9secured to the bearing 2 by a set screw 10 supports radial arms 11 tothe outer ends of which is secured a circular track-way 12, the flange13 of which has cam surfaces 1 dividing the flange into two track-waysof different height. A spider comprising a hub 15 and radial arms 16 issecured to the shaft 1 by a set screw 17, and below these arms 16 issecured a ring 18 provided with guide openings 19 for a series of rods20 said ring being secured to the radial supports 16 by verticalsupports 18 To the lower end of each of the rods 20 is secured a block21 to the outer side of which is journaled a grooved roller 22, saidrollers being adapted to travel on the flanged track- 1 way 12.

At diametrically opposite points two vertical rods 23 are secured to thetrack-way 12 by U-shaped clamps 24: and set screws 25,

said clamps each being provided with a socket 26 to receive the lowerends of the rods 23, and securing set screws 27. At the upper end ofeach of the rods 23 is a collar 28 from which projects a pin 29 uponwhich is mounted a roller 30 adapted to be struck by a tripping lever 31pivotally secured to the stem 32 of a valve arranged within a casing 33to control the flow of liquid through a filling spout 34: adapted toproject into the filling opening of a can 35 or other container. Theliquid supply is from a suit able tank or reservoir indicated as 36 inFig. 2, and connected by a pipe 37 with the valve casing 33.

To the upper end of each of the rods 20 is removably-secured a packageholder (in the present case a can holder), which constitutes an elementof importance in the present invention, and comprises a base 38 providedwith side flanges 39 constituting guards, and projecting seats 40 tosupport the bottom of the can above the base on three sides, the frontside of the can hearing against a stop 41 secured centrally between theside flanges 39, and secured by a bolt 0r rivet 42. The upper side ofthe base 38 of the holder is inclined inward, and the inner ends of theflanges 39 converge to provide a trough-like dripping end for theholder. From the under side of the base 38 depends a socket 43 toreceive the upper end of the rod 20, said rods being guided throughopenings in a ring 44. secured to the outer ends of the spider arms 16.The arms 16 support a drip-pan having a flared edge flange 4:6 andsleeves 17 surrounding the rods 20. The can holders are removablysecured upon the ends of the rods 20 by set screws a6.

The operation of the machine constructed as above described is asfollows: The rotation of the shaft 1 revolves the can-holders and theirsupporting rods 20, and the rollers 22 travel around the circularcam-faced track-way, the cam surfaces 11 causing the raising andlowering of the rods, and the can-holders carried thereon. When the rodis in its elevated position, the filling spout 34 is projected into thefilling opening in the can as shown at the left in Fig. 2, and when therod is lowered by the dropping of the roller 22 to the lower level ofthe track-way as shown at the right in Fig. 2, the can is released fromthe lower end of the filling spout, permitting the filled can to beremoved from its holder. The reservoir 36 and its discharge pipes aresupported in any suitable manner. These elements, as well as the valvemechanism here shown, constitute the subject matter of a separateapplication for Letters Patent, and any other liquid supply means may besubstituted for the means here shown, without afiecting the operation ofthe vertically movable rods and their can-holders. The function of therollers 30 is to trip the levers 31 or other valve-operating mechanism.

What I claim as new is 1. In a package-filling machine, the combinationwith a revoluble shaft, of a fixed circular cam-faced track-way, a hubse- .of said rods adapted to travel on said trackway, and a series ofholders supported upon the upper ends of said rods.

2. A can-holder for filling machines, comprising an inclined base havingside guards or flanges converging at their inner ends,

and projections on said base to support a can above the inclined surfaceof the base.

3. A can-holder for filling machines, comprising an inclined baseprovided with side flanges converging at their inner ends, projectionson said base to support a can above the latter, and a stop adjacent theinner end of said base to engage the can.

4;. In a can-filling machine, the combination with a supporting rod, ofa can-holder comprising a base having a depending socket to receive theupper end of said rod and side guards converging at their inner ends,projections on said base to support a can above the upper surface of thebase, and a stop to limit the inward movement of the can.

In testimony whereof I affix my signature in presence of two witnesses.H
